Soft Chewy Oatmeal Cookies Grandmas Secret Recipe

Frequently Asked Questions

Why are my oatmeal cookies flat and greasy?

Ah, the dreaded flat cookie! There are a couple of culprits here. Firstly, make sure you chill the dough it’s non-negotiable! This solidifies the butter, preventing excessive spreading in the oven. Secondly, ensure your butter isn't too soft (borderline melted).

Finally, measuring your flour accurately will help to get the right consistency for the dough.

Can I make this oatmeal cookie recipe gluten-free?

Absolutely! Swapping out the all-purpose flour for a good quality gluten-free all-purpose flour blend should work a treat. Just be sure to use a blend that contains xanthan gum or guar gum, as these act as binders that mimic gluten's role in giving the cookies structure.

gluten-free baking can be a bit touchy, so keep an eye on the baking time; they might cook a tad faster.

How should I store these oatmeal cookies to keep them fresh?

To keep your cookies as scrummy as the day you baked them, store them in an airtight container at room temperature. They should stay fresh for up to 5 days, but let's be honest, they'll probably be gone way before then! You can also freeze the baked cookies (or even the dough) for longer storage.

Can I add different mix-ins to this oatmeal cookie recipe?

You bet! Feel free to get creative. Chocolate chips (milk, dark, or semi sweet) are always a winner. You could also try chopped nuts (walnuts, pecans, almonds), dried cranberries, shredded coconut, or even a sprinkle of sea salt on top after baking.

Just remember to adjust the total amount of mix-ins to about 1 cup to maintain the right dough-to-add-in ratio.

What does chilling the dough actually do for this oatmeal cookie recipe?

Chilling the dough in this oatmeal cookie recipe is more crucial than queuing up for Wimbledon tickets! It allows the fat (butter) to solidify, which prevents the cookies from spreading too thin and becoming greasy while baking.

It also helps the flavors meld together and intensifies the overall taste, resulting in a chewier, more flavourful cookie. If you're short on time, even 30 minutes in the fridge will make a noticeable difference, but an hour or more is ideal.

My oatmeal cookies are too dry! What did I do wrong?

Oh dear, that's no good! Firstly, double check that you didn’t accidentally overmeasure the flour. A little too much can really dry things out. Overbaking is another common culprit. Keep a close eye on them in the oven; they should be golden around the edges but still slightly soft in the center.

They'll continue to firm up as they cool. Lastly, ensure you're using enough butter/fat in the recipe.
